She said police were told 'possibly two or three inmates assaulted another inmate' who was left with head injuries.

Loveridge will appear in Goulburn Local Court on Wednesday, May 27.

The 21-year-old is serving 14 years for Mr Kelly's manslaughter.

Mr Kelly suffered catastrophic head injuries after Loveridge punched him once in an unprovoked attack at Kings Cross, in Sydney's inner-city, on July 7, 2012.

The 18-year-old's life support was turned off two days later.

Initially, Loveridge was jailed in November 2013 for just four years for manslaughter, which prompted wide-spread public anger.

The Deparment PP launched an appeal against the leniency of the decision, which was upheld and in July 2014 he was handed a lengthier jail time.

In November 2013, a court heard how 19-year-old Loveridge had drunk several cans of Smirnoff double black vodka drinks and shots as he prowled Kings Cross and told a friend 'I swear I’m going to bash someone'.

Mr Kelly, an accounting cadet, was walking with his girlfriend and talking on his mobile phone when he was violently attacked.

Police originally charged Loveridge with murder but he offered to plead guilty to manslaughter.

The earliest Loveridge can be released from jail is November 17, 2022.
